not updating unwritable cache ../config.cache

not updating unwritable cache ../config.cache

[John Wiersba]

I've recently reinstalled full.exe and also the 1/15/99 patches (both binary
and source).  Now I'm trying to build the sources.  My build script looks
like:
   #!/bin/ksh
 
   cd /usr/src/TARGET-OBJ
   /usr/src/dev/configure --prefix=/usr/src/TARGET-INSTALL -v 2>&1 |
                       tee /usr/src/configure.log   
   make         2>&1 | tee /usr/src/make.log
   make install 2>&1 | tee /usr/src/install.log

I'm getting a lot of configure errors which look suspicious:
   not updating unwritable cache ../config.cache

Two things which may be related:

1)  The following never works for me
   [[ -w FILE ]] && echo ok
even if the file *is* writable by me.

2) The id and ls commands work strangely for me:
   > id
      uid=500(administrator) gid=100(everyone) groups=100(everyone)
   > rm -f FILE; touch FILE; ls -l FILE
      -rw-r--r--   1 jrw      JRW             0 Mar 24 15:55 FILE
   > cd /c
   > rm -f FILE; touch FILE; ls -l FILE
      -rw-r--r--   1 winnt    Everyone        0 Mar 24 15:57 FILE
   > cat /etc/passwd  
      WinNT::0:513:::
      Administrator::500:513:::
      Guest::501:513:::
      jrw::544:544:::/bin/ksh
   > cat /etc/group
      Everyone::0:
      JRW::513:
I've lived with this "feature" for a long time, but maybe it's related to
this problem?

Thanks,

Could this be the old "I'm part of the Administrator group" so the Administrator
User owns all files, not me syndrome?

Create a new user id which does not have Adminstrator Priveledges and try
building again.

This is known.  You won't get the test to work unless the permission you
are checking is available "across the board".  Corinna has made some 
changes to address this under NT/NTFS in later snapshots but that won't
be any solution for 9x platforms AFAIK.  You might want to check your umask
setting and make sure it doesn't mask out write permissions for group 
and others...

Options that I know of that exist for NT include:

   - set ntea in you CYGWIN environment variable (actually I'm not sure this
     addresses the test problem).  This has the detriment of creating a file
     EA DATA. SF at the root of FAT drives that grows very quickly and is 
     hard to get rid of (permissions of all files are saved here).  No such
     file is required or used for NTFS.

   - Use a recent snapshot with CYGWIN set to ntsec, following Corinna's 
     instructions exactly.  This works on NTFS drives only.


Have you checked with others on this list with regard to Perl's problem 
here.  I haven't watched that closely but it seems to me I recall others
on this list reporting Perl running well under Cygwin.  I haven't 
investigated Cygwin Perl myself.

Generally speaking, snapshots are for development only.  They don't get 
"saved".  I expect you'd find using ntsec with a recent snapshot would 
resolve the problem but I don't know for sure.  Of course, if you try this,
you will be working with the current stuff, so you will run a risk.  Still,
if you really want to find a solution for this, you may be interested in 
actually looking at the code in the cygwin DLL and trying to see what's
going on, in which case you need current source.;-)  Also, a mitigating 
factor might be that the current thought is that a new net release is 
pending, which means that the "bleeding edge" may be more stable at this
point than it would be otherwise.  You're best bet always is to back up the
version you have before moving forward, in case you decide you need to fall
back.

My umask was set to 02.  I changed it to 0 and created a new file, but -w
still fails.

I saw the "across the board" mentioned in the faq or user guide.  Is there a
work-around?  Perl's cpan command is totally broken because of this.

Is it fixed in one of the later snapshots?  I don't want to be on the
bleeding edge, but I do want to be able to compile the cygwin code on my
machine.  Is there a relatively stable snapshot I should upgrade to?

Thanks,
John

OK, how do I tell which group I'm part of?  The groups command says
"everyone".  I didn't set up my machine (our computer services group did).
I don't think I can set up a new user id.

But notice that files created by me on c: (a FAT drive) are owned by
winnt/everyone whereas files created by me on d; (an NTFS drive) are owned
by jrw/JRW.

I do know that the code _generated_ by mingw32 do not use cygwin1.dll; that's effectively the reason why it exists :-)


But I think I've read that the "native" mingw32 toolset was in fact running under cygwin and using cygwin1.dll... but perhaps this is only true for the mingw32 cygwin-add-on, not for the independently distributed one. 

Forgive me if I'm not really sure, but for now quite a long time I'm using always mingw32 for all my NT development, but I'm using a cross-compiler running on UNIX (usually Linux, but I've also built the cross-toolset on other flavors of UNIX, like Solaris, where it runs fine).

Supplementary groups don't work, right? (Just making sure I
understand what's going on.)

Anyway, given that NT doesn't quite seem to see a difference
between user and group ids (Novell is similar, incidentally), I
decided

	mkdir /etc
	cd /etc
	( mkpasswd -l -g ; mkgroup -l ) | sort -n -t: +2 > common
	ln common passwd
	ln common group

was the way to go here.

Using the 19990929 cygwin1.dll, this seems to work now. Thanks!

One more question: I see directories getting the other t bit set.
What does this mean?

Hummm... just a thought:
   genattrtab.o, genattrtab.exe, i386.o, getpwd.o were all created by compiling with some version of gcc installed on your NT box

   insn-attrtab.c is generated by genattrtab.exe, but I think the make rule is like "genattrtab > insn-attrtab.c", so the fact is in fact created by bash (or ash)

   s-attrtab is created by "touch s-attrtab" so is created also by bash/ash (or even directly by make perhaps).


What I'm wondering is that perhaps bash/ash is doing some special things to ensure that the generated files are correctly owned by the effective user, but that other programs may be fooled and attribute rights to the administrator?

Could it be that make do not re-export everything that's passed in the environment? I've header that some versions of gnu-make make some non-usual things in this area.

Why? mingw gcc is compiled and run in the cygwin environment I think, so go through cygwin1.dll that handles ntsec.

You can only have one primary group which is the group that
is your default group for file creation.
`newgrp' isn't supported yet but maybe later (shouldn't be too
complex).

This isn't completely right! A group may be used as owner of an
object but a user must not be used as "group" in a security
descriptor. So users shouldn't reside in the group file though
they wouldn't disturb there.

Grin! The 't' bit is the sticky bit that is used in a linux style
manner. It only make sense for directories and it's typically set
on /tmp (rwxrwxrwt) and has the effect, that anybody may read and
write in /tmp but he/she can't erase files of other users.

Unfortunately, the sticky bit is set in ntsec by mistake. I had
corrected this a few days ago and the _next_ snapshot after yours
(19991001) behaves correctly.

Looks like as if you have edited with ntsec but compiled without it.
Would you be so kind to check this out?
Another one: Are you sure to have only one cygwin1.dll in $PATH
search path?

Yep. But this should have a simple solution. I'm using ntsec each day
and the above is not what happens to me.

"ntsec" is definitely the wrong option here.  If you want extended attributes
you can turn this on with "ntea".  CAUTION: doing this on a FAT partition will
cause file in the root of all FAT drives accessed by cygwin to grow a large
file that isn't easily delete-able to be created.  Also, all diskettes will
have the "EA DATA" system file as well.

Kai is already in the administrators group which makes him an administrator. 
This also makes all files created owned by the adminstrator.  The real problem
is the test -w bug.

I suggest trying a more recent snapshot.  Caveat: save any files that you
replace as you may need to backout.

Mingw32 gcc and binutils _DO_NOT_ use the cygwin1.dll.  That is the reason it
exists.  Instead it uses the runtime from M$.  So, Kai is correct that Mingw32
doesn't care about ntsec as far as the it's implementation within cygwin1.dll.

group #544 is Administrators
so test is owned by Administrators, group "Kein" ("None"? -- do an ls
-lan. This should show  "-rw-r--r--   1 544     513    .....". Group
#513 is "None" in english.) I believe you have discovered a *different*
problem, which is a bug. Echo doesn't seem to check permissions. If you
do a 

if [ -w test ]; then echo writable; else echo non-writable; fi

you should see the results I described.

Oh yeah. Sorry. I forgot that the only thing umask does is *remove*
privileges from created files. If the default access mode is -rw-rw-rw-
and you have a umask of 022, then the file will be created with
group-write and all-write access disabled (-rw-r--r--). By setting umask
to 000, you have shown that the default access mode is -rw-r--r--. You
can't use umask to *add* priveleges (such as group-write). There is a
way to do that, but I don't remember what it was...

However, if you have administrator priveleges, then you can certainly
create a normal user account. If you *choose* not to do this, that is
your right and your decision.

I don't know enough about ntsec and the latest snapshots to offer useful
advice; Corinna has explained ntsec earlier in this thread.

Well, it's "test -w" failing. Obviously because of this:

bash-2.02$ touch test
bash-2.02$ ls -la test
-rw-r--r--   1 544      Kein            0 Oct  5 09:57 test
bash-2.02$ id
uid=1000(kai) gid=513(Kein) groups=513(Kein)
bash-2.02$ chmod a+w test
bash-2.02$ ls -la test
-rw-r--r--   1 544      Kein            0 Oct  5 09:57 test
bash-2.02$

But that just shifts the confusion somewhere else.

'ntsec' is definitely not the wrong option. 'ntsec' is the better
choice if you are using NTFS filesystems. 'ntea' is a hack that uses
a cryptic WinNT method for creating and reading hidden file contents.
It's hard to erase them later if you need to do so. Moreover the
method to save this so called 'extended attributes' on FAT partitions
is an impertinence.

If you are working with FAT, unfortunately, try a newer snapshot of
cygwin1.dll. The simulated file ownership should do it for you.
And don't use an account, that is member of the administrators group.
In this case the file owner and the user are diverging.

Corinna

Huh?! Echo (rather, bash) _should not_ check permissions. It
should just try to do what it's told to do.

Well yes, and _that_ is the bug.

Under Unix, this is typically done with supplementary groups (from our server:
$ id
uid=1000(kai) gid=1000(kai) groups=1000(kai),20(dialout),33(www-data),50(staff),102(entwicklung),104(everyone)
$
), but of course that isn't _exactly_ what NT does.

The usual solution (even under Unix) is that most accesses just try
and see if the kernel lets them through, and stuff like test uses
access() which maps, again, to a system call so the kernel
determines if the access in question is possible. The stat() results
should only ever be used for security outside the kernel in
extraordinary circumstances.

Of course, cygwin _could_ define parts of newlib as kernel, but in
this particular case, that seems pointless. Security that only works
for programs compiled with cygwin seems futile.

On the other hand, I don't know what the Win32 analog to access()
would be. Maybe the only choice is to actually try to open the file
(except for the existence test, of course).

If I create a different account, then NT will keep me from important
applications, I'll have trouble getting at my mail, I'll have trouble
mapping network drives, ...

Not really unsolvable, but a _huge_ amount of work.

All of these were created from the same "make bootstrap" run.

Well, I have some cygwin1.dll.something in the same directory as
the one to use, but I wouldn't expect those to be used.

(check environment)

And yes, it's exported (actually set by the .bat that starts bash).

Hmm. Maybe someone there clobbers the CYGWIN variable? <find

Oh! Silly of me. Of _course_. It's the mingw gcc. Obviously, it won't
care about ntsec.

What I don't understand is how this happens. After all, I created the
file. And I _can_ write to the file. Something is very wrong here.

I don't consider that an option. Besides, I don't get any extra rights
that way.

Use mkpasswd and mkgroup to create /etc/passwd and /etc/group files.
In the current snapshots, the following rules are important:

- Dont use user and/or group names that are different from the
  NT account names.
  Ever:  administrators::544:
  Never: admins::544:
- Typically, group 513 is your primary group. This is `None' outside
  and `Domain Users' inside of NT domains.
  The primary group membership isn't important for `ntsec', so you
  may change your group entry in /etc/passwd to, e.g., administrators
  group:

	kai::1000:544:Kai Henningsen:/home/kai:/bin/sh

- Use `umask' command in your profile, e.g.: `umask 022'.

Try a `touch foo' and `ls -l foo'. Without `ntsec' you'll get:

  -rw-r--r-- 1 administ none        0 Oct 5 20:00 foo

With `ntsec':

  -rw-r--r-- 1 kai      administ    0 Oct 5 20:00 foo

When you try `ntsec' you will see that this problem is gone.
Maybe, you get other ones... but I'm working hard in making
`ntsec' better.

And last but not least:

No, NT `feature' ;-}
If a user is member of the administrators group, the administrators
group will be the owner of _every_ object that is created by him/her
(including files, processes, semaphores,...)
_if_ _not_ _explicitly_ _changed_! This job is done by `ntsec'.

It's unwritable by anyone other the owner of the file.

If you're using a recent snapshot, setting "ntsec" in your CYGWIN
variable may cause chmod to work correctly. (I say "may" because I
really don't know. I don't run NT.) Historically, chmod returns
without error on Cygwin but does nothing.

You (UID 1000) don't own the file, UID 544 (administrator) owns
it. (I guess you already knew that. :-)

You need to login as administrator or wait for someone else to
provide information on how to enable ntsec and Unix permissions.

I do know that the code _generated_ by mingw32 do not use cygwin1.dll; that's effectively the reason why it exists :-)


But I think I've read that the "native" mingw32 toolset was in fact running under cygwin and using cygwin1.dll... but perhaps this is only true for the mingw32 cygwin-add-on, not for the independently distributed one. 

Forgive me if I'm not really sure, but for now quite a long time I'm using always mingw32 for all my NT development, but I'm using a cross-compiler running on UNIX (usually Linux, but I've also built the cross-toolset on other flavors of UNIX, like Solaris, where it runs fine).

Mingw32 gcc and binutils _DO_NOT_ use the cygwin1.dll.  That is the reason it
exists.  Instead it uses the runtime from M$.  So, Kai is correct that Mingw32
doesn't care about ntsec as far as the it's implementation within cygwin1.dll.

Hummm... just a thought:
   genattrtab.o, genattrtab.exe, i386.o, getpwd.o were all created by compiling with some version of gcc installed on your NT box

   insn-attrtab.c is generated by genattrtab.exe, but I think the make rule is like "genattrtab > insn-attrtab.c", so the fact is in fact created by bash (or ash)

   s-attrtab is created by "touch s-attrtab" so is created also by bash/ash (or even directly by make perhaps).


What I'm wondering is that perhaps bash/ash is doing some special things to ensure that the generated files are correctly owned by the effective user, but that other programs may be fooled and attribute rights to the administrator?

Could it be that make do not re-export everything that's passed in the environment? I've header that some versions of gnu-make make some non-usual things in this area.

Why? mingw gcc is compiled and run in the cygwin environment I think, so go through cygwin1.dll that handles ntsec.

Huh?! Echo (rather, bash) _should not_ check permissions. It
should just try to do what it's told to do.

Well yes, and _that_ is the bug.

Under Unix, this is typically done with supplementary groups (from our server:
$ id
uid=1000(kai) gid=1000(kai) groups=1000(kai),20(dialout),33(www-data),50(staff),102(entwicklung),104(everyone)
$
), but of course that isn't _exactly_ what NT does.

The usual solution (even under Unix) is that most accesses just try
and see if the kernel lets them through, and stuff like test uses
access() which maps, again, to a system call so the kernel
determines if the access in question is possible. The stat() results
should only ever be used for security outside the kernel in
extraordinary circumstances.

Of course, cygwin _could_ define parts of newlib as kernel, but in
this particular case, that seems pointless. Security that only works
for programs compiled with cygwin seems futile.

On the other hand, I don't know what the Win32 analog to access()
would be. Maybe the only choice is to actually try to open the file
(except for the existence test, of course).

If I create a different account, then NT will keep me from important
applications, I'll have trouble getting at my mail, I'll have trouble
mapping network drives, ...

Not really unsolvable, but a _huge_ amount of work.

All of these were created from the same "make bootstrap" run.
That's what I find so confusing.

Well, I have some cygwin1.dll.something in the same directory as
the one to use, but I wouldn't expect those to be used.

(check environment)

And yes, it's exported (actually set by the .bat that starts bash).

Hmm. Maybe someone there clobbers the CYGWIN variable? <find

Oh! Silly of me. Of _course_. It's the mingw gcc. Obviously, it won't

group #544 is Administrators
so test is owned by Administrators, group "Kein" ("None"? -- do an ls
-lan. This should show  "-rw-r--r--   1 544     513    .....". Group
#513 is "None" in english.) I believe you have discovered a *different*

Oh yeah. Sorry. I forgot that the only thing umask does is *remove*
privileges from created files. If the default access mode is -rw-rw-rw-
and you have a umask of 022, then the file will be created with
group-write and all-write access disabled (-rw-r--r--). By setting umask
to 000, you have shown that the default access mode is -rw-r--r--. You
can't use umask to *add* priveleges (such as group-write). There is a
way to do that, but I don't remember what it was...

However, if you have administrator priveleges, then you can certainly
create a normal user account. If you *choose* not to do this, that is
your right and your decision.

I don't know enough about ntsec and the latest snapshots to offer useful
advice; Corinna has explained ntsec earlier in this thread.

You can only have one primary group which is the group that
is your default group for file creation.
`newgrp' isn't supported yet but maybe later (shouldn't be too
complex).

This isn't completely right! A group may be used as owner of an
object but a user must not be used as "group" in a security
descriptor. So users shouldn't reside in the group file though
they wouldn't disturb there.

Grin! The 't' bit is the sticky bit that is used in a linux style
manner. It only make sense for directories and it's typically set
on /tmp (rwxrwxrwt) and has the effect, that anybody may read and
write in /tmp but he/she can't erase files of other users.

Unfortunately, the sticky bit is set in ntsec by mistake. I had
corrected this a few days ago and the _next_ snapshot after yours
(19991001) behaves correctly.

Looks like as if you have edited with ntsec but compiled without it.
Would you be so kind to check this out?
Another one: Are you sure to have only one cygwin1.dll in $PATH
search path?

Yep. But this should have a simple solution. I'm using ntsec each day
and the above is not what happens to me.

Supplementary groups don't work, right? (Just making sure I
understand what's going on.)

Anyway, given that NT doesn't quite seem to see a difference
between user and group ids (Novell is similar, incidentally), I
decided

	mkdir /etc
	cd /etc
	( mkpasswd -l -g ; mkgroup -l ) | sort -n -t: +2 > common
	ln common passwd
	ln common group

was the way to go here.

Using the 19990929 cygwin1.dll, this seems to work now. Thanks!

One more question: I see directories getting the other t bit set.
What does this mean?

Use mkpasswd and mkgroup to create /etc/passwd and /etc/group files.
In the current snapshots, the following rules are important:

- Dont use user and/or group names that are different from the
  NT account names.
  Ever:  administrators::544:
  Never: admins::544:
- Typically, group 513 is your primary group. This is `None' outside
  and `Domain Users' inside of NT domains.
  The primary group membership isn't important for `ntsec', so you
  may change your group entry in /etc/passwd to, e.g., administrators
  group:

	kai::1000:544:Kai Henningsen:/home/kai:/bin/sh

- Use `umask' command in your profile, e.g.: `umask 022'.

Try a `touch foo' and `ls -l foo'. Without `ntsec' you'll get:

  -rw-r--r-- 1 administ none        0 Oct 5 20:00 foo

With `ntsec':

  -rw-r--r-- 1 kai      administ    0 Oct 5 20:00 foo

When you try `ntsec' you will see that this problem is gone.
Maybe, you get other ones... but I'm working hard in making
`ntsec' better.

And last but not least:
- Constructive feedback always welcome.

No, NT `feature' ;-}
If a user is member of the administrators group, the administrators
group will be the owner of _every_ object that is created by him/her
(including files, processes, semaphores,...)
_if_ _not_ _explicitly_ _changed_! This job is done by `ntsec'.

'ntsec' is definitely not the wrong option. 'ntsec' is the better
choice if you are using NTFS filesystems. 'ntea' is a hack that uses
a cryptic WinNT method for creating and reading hidden file contents.
It's hard to erase them later if you need to do so. Moreover the
method to save this so called 'extended attributes' on FAT partitions
is an impertinence.

If you are working with FAT, unfortunately, try a newer snapshot of
cygwin1.dll. The simulated file ownership should do it for you.
And don't use an account, that is member of the administrators group.
In this case the file owner and the user are diverging.

Corinna

This is a reported and known bug.  Have you tried it with a snapshot?

"ntsec" is definitely the wrong option here.  If you want extended attributes
you can turn this on with "ntea".  CAUTION: doing this on a FAT partition will
cause file in the root of all FAT drives accessed by cygwin to grow a large
file that isn't easily delete-able to be created.  Also, all diskettes will
have the "EA DATA" system file as well.

Kai is already in the administrators group which makes him an administrator. 
This also makes all files created owned by the adminstrator.  The real problem
is the test -w bug.

I suggest trying a more recent snapshot.  Caveat: save any files that you
replace as you may need to backout.

What I don't understand is how this happens. After all, I created the
file. And I _can_ write to the file. Something is very wrong here.

> You need to login as administrator

I don't consider that an option. Besides, I don't get any extra rights
that way.

It's unwritable by anyone other the owner of the file.

If you're using a recent snapshot, setting "ntsec" in your CYGWIN
variable may cause chmod to work correctly. (I say "may" because I
really don't know. I don't run NT.) Historically, chmod returns
without error on Cygwin but does nothing.

You (UID 1000) don't own the file, UID 544 (administrator) owns
it. (I guess you already knew that. :-)

You need to login as administrator or wait for someone else to
provide information on how to enable ntsec and Unix permissions.

Well, it's "test -w" failing. Obviously because of this:

bash-2.02$ touch test
bash-2.02$ ls -la test
-rw-r--r--   1 544      Kein            0 Oct  5 09:57 test
bash-2.02$ id
uid=1000(kai) gid=513(Kein) groups=513(Kein)
bash-2.02$ chmod a+w test
bash-2.02$ ls -la test
-rw-r--r--   1 544      Kein            0 Oct  5 09:57 test
bash-2.02$

But that just shifts the confusion somewhere else.

I'm seeing this every time I ./configure something. Anybody know
what is going on?

bash-2.02$ find . -name "*cach*" -ls
363270609    0 -rw-r--r--   1 544      Kein            0 Oct 04 14:11 ./config.cache
bash-2.02$

Sure doesn't _look_ unwritable. Besides, the very same script just
created it.
